I have a NS-PDVD8 . I purchased DEC 2006. I used it in April 2007 and then again in Jan.2008. When I went TO use March -2008 I received message NO DISCwhen attempting to play DVD.i messed with for an hour by rebooting and and dusting with compressed air.No help
next day I tried a CD and after very long loading time played music.
after I let it run for an hour I attempted DVD but same response.NO DISC
I cleaned the optical lens with a damp soft cloth and dried with soft cloth ( I do not recommend using a cloth but I was fed up and needed the player for flight next day) I believe you can purchase a cleaner kit.
I also ran the lens back and forth 5 or 6 times to make sure it could move fully along track.I heard clicking and wondered if this was ever going to run again.
I tried a CD first and the Cd loaded almost immediately and played
Next I tried a DVD and loaded successfully and played entire movie.
I turnred on and off about 10 times and reloaded movie without any problem.
